batteries should be replaced within a couple of weeks to ensure
continued safety of your RAM entries.
To replace the batteries, turn the unit
over on a soft surface and remove the
battery compartment cover (see Figure
4.1). A small tool, such as a
screwdriver, may be n'ecessary in
unlatching the tab. Be careful not to
break this tab. Replace the batteries
with three high quality AA size "heavy
duty" or alkaline batteries. A
capacitor will keep the memory alive
for about 30 seconds while changing the
batteries, thus do not remove the old Figure 4.1 - Battery positioning
ones until the new ones are ready for
installation. Alternatively, it is permissible to the power
cable plugged in and the power on while changing the batteries,
in which case memory will be retained as long as power is on.
Be sure to insert the new batteries in the directions indicated
by markings in the bottom of the battery compartment. Incorrect
insertion won't damage anything but the memory won't receive any
power from the batteries.
Most quality brand-name batteries now have "sell by" dates
printed on their packages. Carbon-zinc batteries will last for
at least a year after installation while alkaline batteries
should last for at least 2 years provided they are installed
before the date on the package. Rechargeable batteries should
not be used; the K2000 will not recharge them and their life
after charging on an external charger will be only a few months.
Battery life is not significantly increased by leaving your
K2000 on all the time; batteries may even suffer heat
degradation if the K2000 is left on continuously.
USER CALLABLE DIAGNOSTICS
If difficulty is experiences with a third-party switch pedal or
control pedal, the built-in user callable diagnostic program may
help in diagnosing the problem. This program will display on
the LCD exactly what the K2000's internal computer sees when the
pedal is used. This can help determine if there really is a
physical problem with the pedal or merely a programming problem
in your program or setup. The diagnostic can be used to check
out the keyboard and built-in controls as well.
To enter the diagnostic program, simply press the
buttons simultaneously when in the Program Mode.
